摘要： A casting furnace for manufacturing a metal casting comprises an interior chamber and a secondary chamber through which the metal casting passes from the interior chamber into external atmosphere. A seal along the secondary chamber surrounds and seals against the metal casting to separate the interior chamber from the external atmosphere in a manner which allows for an extended period of continuous casting. A force producing mechanism typically forces the seal against the metal casting. Multiple seals may be used sequentially to increase the duration of the sealing capability and the continuous casting process.

摘要： A seal for a continuous casting furnace having a melting chamber with a mold therein for producing a metal cast includes a passage between the melting chamber and external atmosphere. As the cast moves through the passage, the cast outer surface and the passage inner surface define therebetween a reservoir for containing liquid glass or other molten material to prevent the external atmosphere from entering the melting chamber. Particulate material fed into the reservoir is melted by heat from the cast to form the molten material. The molten material coats the cast as it moves through the passage and solidifies to form a coating to protect the hot cast from reacting with the external atmosphere. Preferably, the mold has an inner surface with a cross-sectional shape to define a cross-sectional shape of the cast outer surface whereby these cross-sectional shapes are substantially the same as a cross-sectional shape of the passage inner surface.

摘要： In a lubricant composition suitable for use in the manufacture of aluminum alloys comprising a lubricant base, the improvement wherein the lubricant composition further comprises: an effective amount of water, surfactant, and a high viscosity organic material having a low vapor pressure. It is believed that this mixture provides a method for uniformly distributing the surface oxide at the meniscus for casting applications and increasing meniscus stability. Uniform distribution of the oxide and increased stability at the meniscus reduces vertical fold formation that can lead to cracks in the aluminum ingot. In addition, the mixture promotes uniform heat transfer around the mold. Uniform heat transfer around the mold allows the solidifying aluminum alloy to stay in contact with the mold longer and form stronger ingot shells. A process for continuous or semi-continuous casting of aluminum alloys via the use of this lubricant composition is also disclosed.

摘要： The invention relates to a hot-top mold for a strand casting apparatus, consisting of a hot-top, which lies on the upper side of a parting agent distributor and presses it with its underside against the surface of a mold, an overhang being formed on the radially inner surface of the hot-top, which protrudes beyond the parting agent distributor in the direction of take off of the strand, the hot-top being centered and held by an outer ring, which is releasably fastened to the mold. The mold surrounds a function ring toward the bearing surface of the mold which, together with the parting agent distributor, forms function surfaces with adjustable roughness on the surfaces. In the parting agent distributor, radial channels are formed at the upper side and the underside, the channel cross sections at the upper side and the underside being in a ratio of 1:3 to 1:5 to one another.

摘要： An ingot I made of a light alloy is produced using a continuous casting apparatus including a cylindrical water-cooled casting mold which is disposed immediately below a spout having an upward-turned molten metal receiving port and a downward-turned molten metal outlet, and which has an inside radius r1 larger than an inside radius r2 of the molten metal outlet, and lubricating oil discharge passages provided below the spout to supply a lubricating oil to between the water-cooled casting mold 13 and a molten metal m brought into contact with the water-cooled casting mold. In this production, a lubricating oil having a vaporization rate of 30% or more at 300° is used, and an annular gas accumulation for spacing the molten metal apart from outlets of the lubricating oil discharge passages is defined below an annular protrusion of the spout by vaporization of the lubricating oil. Thus, it is possible to avoid the generation of a casting skin failure in a light alloy ingot due to the outlets of the lubricating oil discharge passages.
